FOUNTAIN BRUSH.

Application filed March 23,

Among its objects is an improved valve, and a novel arrangement of brush parts which produces increased efficiency in use. It should be understood that the cleaning fluid used in this class of brush is volatile, drying oli" immediately on application to the type. My valve arrangement is peculiarly adapted to prevent leakage from the container by evaporation. Furthermore, the valve is constructed so as to permit the bristles to be set at right angles to the combined handle and container, which increases the efficiency of the brush.

In Figure 1, the combined handle and container 1 is a glass bottleffor the main supply of cleaning fluid, which bottle is provided with a threaded neck ure 3), to which is attached the brass cap 2 for an auxiliary supply of cleaning fluid from said main supply, whichcap is recessed at 23v (as shown in Fig. 4), intol which'is soldered the tube 3 having the bristles 4, permeable to liquid, secured in its end. Into the other end of the tube 3 is inserted the elastic stopper shown in Figure 5, which I prefer to make of leather. The stopper 7 engages with the aperture 12 (shown in Fig. 3), normally closing it, as shown at-12 in Figure 4. To prevent the leather from becoming loose from shrinkage or wear, I provide the spring strips 9-9 shown in Figure 5, which are held by the `tube firmly against the flat sides of the stopper 7 by the wall of the tube 3 when the stopper is inserted in the tube. These strips being flat are spaced away from the inside wall of the tube 3 as shown at 9-9 the leather member 7 then enfrcm passing trein the cap 2` `against the lip of the (shown in Figwith but little if any lbrush under certain conditions, which I will l1927.

and the container 1 into the tube 3. By rotating the stopper 7 by meansy of the stopper handle 5 secured to the end thereof the leather stopper is moved out of engagement or registry with the aperture 12, and fluid passes through the aperture 12 and flows to the bristles through the space in the tube 3 between the strips 9-9 and the wall of the tube. It will be apparent that the stopper 7 may be rotated in the tube 3 to open the aperture 12, or to close it, to any desired degree, and by this means control the amount of fluid flowing from the fluid container to the bristles.

rllhe stopper handle 5 is oval so as to furnish sufcient leverage for rotating the stopper, and the strips 9-9 are securely held in place between the stopper handle and the leather stopper. Opening and closing of he valve is very readily eeoted in the manner described, but it is almost as Y convenient to simply withdraw the stopper from the tube sufcientlyfto move it out of engagement withthe aperture 12. y

Referring to FigureB, it will be seen that the. neck of the ycontainer 1 is threaded and provided with the screw-top cap 8, which has the washerv 10 inside of it to engage container. The cap and washer are apertured at 11, soas to permit the fluid to flow into the cap 2, which issoldered onto the cap 8. Obviously the tube 3 could be readily soldered onto the screw-top cap 8, thus omitting the cap 2, loss in efiiciency of the presently describe. The structure shown makes an attractive appearance when the brass cap 2 is nickel plated, and in using this structure I am able to employ the ordinary screw-top cap 8, which is inexpensive.

In Figure 7 I show a modified brush, in

which the modified stopper 18, shown in Figure 8 is used. Thestopper is reinforced with the bowed spring strip 21, having the turned in ends 19-19 to hold it in place against the flat face of the stopper 18. The tube 14 (Figure 6) is slotted intermediate of its ends at 22, and when the stopper `18 is inserted into the tube the handle 20, which is an ordinary eye screw, is inserted into the slot 22 and screwed into the stopper. The slot 22 permits the handle to be moved so as to cause the stopper to be rotated in the tube v14 so as to open and close the aperture 17, inthe same manner as 'already described eennectien with the stopper in Fig. 5. In Figure 6 the container 13 is a piece of brass tube spun in at one end to form the base 23, which is recessed to receive the tube 18, held in place by solder; in fact the end of the tube 13, spun in to form the base 23 is substantially the same as the end of the cap 2 as shown in Figure 4, the base 23 being characteristic of both. There is some advantage in the two-ended brush arrangement shown in Figure 6; it is practicable with it to first clean the type with one of the brushes thoroughly saturated with the fluid, and still have in reservel the dry bristles at the other end for brushing off particles of lint and dirt not completely removed by the wet brush. To make this brush still more attractive, I provide detachable brushes ,the bristles 16-16',

ypermeable to liquid, being inserted into the tubular holders 15-15, which respectively telescope into the ends of the tube 14.

It is not my intention to limit my invention to the precise constructions and arrangements shown in the drawings, it being apparent that such may be varied without departing from the spirit and scope ot my'invention. For example, instead of the leather stopper reinforced with springy strip material, as shown in Figs. 5 8, I have usedl a stopper made of a piece of tubing split up the side to give it resiliency so that when telescoped into the brush-holder tube 3, Fig. 1 it will engage very closely against the outlet aperture through the side of the brush-holder tube; this kindot stopper has the advantage of out--wearing the leather. Again in the drawing I show the brush-holder tubes 3 (in. Figures l, 2, 3 and 4) and 14 (in Figures 6 and 7) positioned at substantially right angles to the vertical axis of the containers l and 13, respectively; they may, however, be positioned parallel with the vertical axis of the containers and still retain the main advantage ot' having the outlet aperture in the side thereof positioned intermediate ot the ends oi the brush-holder tubes, it being understood, of course, that the main advantage here referred to residesin the arrangement which I have here embodied for conducting the iiuid through the side of the brush-holder tube and for controlling its flow. So that as to the exact arrangement oi'l parts in relay tion to the outlet aperture positioned intermediate of the ends of the brush-holder tube I desire to be limited only by the scope of the appended claims.

Having thus described my invention, what I desire to claim is:

1. In combination, a liuid container havling a distributing stopper a transverse base,

a round tube secured crosswise to said base, there being an outlet aperture through said base and through the wall of the tube where secured to the base for the flow of liquid' from the container into the tube, bristles at the end of the tube, said stopper being mounted in the tube and being adapted when in normal position to engage against the outlet aperture and against the wall of the tube opposite the outlet aperture, said stopper having its sides intermediate said engaging portions spaced away from the wall of the tube and said stopper being rotatable in the tube, a metal strip positioned between the side ot' the stopper and the wall of the tube, said strip being secured to the stopper and being normally flexed therefrom and rotatable therewith and being substantially flat whereby when the stopper is rotated from its normal position in the tube. to cause said flat strip to be opposite the outlet aperture liquid wiIl flow through the outlet aperture and through the space between the fiat strip and the wall of the tube to the bristles, said stopper being frictionally held in said tube due tothe llexure ot said strip, and grasping mea-ns associated with the stopper for rotating the latter in the tube.

2. In a brush of the class described, a fluid container having a distributing stopper and a transverse base, said base having a recess therein, a round tube secured crosswise in said recess, there being an outlet, aperture through the base and through the wall `of the tube for the How of liquid from the container into.` the tube, bristles provided at one end of the tube, said distributing stopper being mounted in the other end of the tube and being elastic and adapted when fully inserted into the tube to engage against the outlet aperture and to be withdrawn from the tube sufficiently to move it out of engagement with the outlet aperture to permit liquid to flow through the outlet aperture into the tube and to the bristles, and grasping means at the outer ends of the stopper for operating the latter.

3. In a brush of the class described, a bottle having a threaded neck, a screw-top in threaded engagement on the neck, there being a. central opening in the upper end of thescrew-top for the flow of fluid, a cap secured at its open end tov the screw-top and enclosing said central opening, thereby forming a chamber for receiving iuid from the bottle, acylindrical tube secured cross- Wise on the upper end of said cap, an outlet aperture through the upper end of the cap and through the side or' the tube, bristles at the end of the tube and means for controllingthe flow of Huid through said outlet aperture, said means including a plug of elastic material rotatably mounted in the tube and al strip ot spring metal housed between the tube and the plug.

4. In a brush of the class described, a cap having a recess in its outer end, a cylindrical tube secured in said recess crosswise of the cap, an outlet aperture through the end of the cap and through the side of the tube,

bristles at the end of the tube, means for controlling the How of fluid through said outlet aperture, said means including a plug of elastic material rotatably mounted in the tube and adapted to engage normally against the outlet aperture, and a lat strip of spring metal housed between the plug and the tube, said flat strip being secured to the plug and adapted to increase the frictional engagement ol the plug with the tube.

5. In a device for applying type-cleaning liuid, a cylindrical tube having an aperture through its side, a distributing stopper rotatably mounted in the tube and controlling the flow of fluid, said stopper comprising a flatsided elastic plug and a fiat strip of spring metal housed between the flat side of the plug and the tube, said plug normally engaging against the aperture and said strip being normally bent outwardly from the side of the plug whereby insertion of the stopper into the tube lexes the strip whereby increasing the frictional engagement of the plug against the aperture, a handle to turn the stopper for registering the fiat strip with the aperture 'for the flow of fluid from the latter, and bristles at the outer end of the tube.

6. In a device for applying cleaning Huid to typewriter type, a cylindrical tube having an aperture through its side and being of equal diameter throughout its length, a distributing stopper rotatably mounted in the tube and controlling the flow of fluid, said stopper comprising an elastic plug flat on two opposite sides and a flat strip of spring metal housed between each flat side of the plug and the tube, said plug normally engaging against the aperture, each of said flat strips being normally bent outwardly from the side of the plug whereby insertion ol the stopper into the tube tleXes the strips thereby increasing the frictional engagement of the plug against the aperture, a handle for turning the stopper for registering either ot the flat strips with the aperture, and bristles at the end of the tube.
